ATI RN

Human Growth and Development Final Exam

1. Where does the male produce sperm, and where are these glands located?

A. penis; scrotum
B. scrotum; penis
C. testes; penis
D. testes; scrotum

Correct answer: D

Rationale: The male produces sperm in the testes, which are two glands located in the scrotum. The scrotum is the external sac that houses and protects the testes, allowing for optimal temperature regulation to support sperm production. Choice A is incorrect because sperm production does not occur in the penis. Choice B is incorrect because the scrotum houses the testes, not the penis. Choice C is incorrect because sperm is produced in the testes, not the penis.

2. An experimental design __________.

A. allows researchers to gather information in natural life circumstances without altering the participants' experiences
B. looks at relationships between participants' characteristics and their behavior or development
C. permits inferences about cause and effect because researchers evenhandedly assign people to treatment conditions
D. has one major limitation: researchers cannot infer cause and effect

Correct answer: C

Rationale: An experimental design permits inferences about cause and effect because researchers evenhandedly assign people to treatment conditions. This means that researchers can manipulate certain variables and observe the effects on participants, allowing them to determine causation between variables. This is a key strength of experimental research designs. Choices A, B, and D are incorrect because they do not accurately describe the primary purpose or strength of experimental designs. Experimental designs do not focus on gathering information in natural life circumstances (A), looking at relationships between characteristics and behavior (B), or have the limitation of not being able to infer cause and effect (D).

3. Katie wonders when she will first be able to hear her fetus's heartbeat through a stethoscope. You tell her that this should happen by the __________.

A. fourth week of pregnancy
B. third month of pregnancy
C. end of the second trimester
D. beginning of the third trimester

Correct answer: B

Rationale: The correct answer is the third month of pregnancy (choice B). During the third month of pregnancy, which is around 9-12 weeks, a fetal heartbeat can typically be heard using a stethoscope. This is an exciting milestone for expectant parents as it provides reassurance about the baby's well-being. Choices A, C, and D are incorrect because by the fourth week of pregnancy, the fetal heartbeat is not usually detectable with a stethoscope. The end of the second trimester and the beginning of the third trimester are too late in the pregnancy timeline for this milestone.

4. In a correlational design, researchers __________.

A. gather information on individuals without altering their experiences
B. divide events and behaviors of interest into two types: dependent and independent variables
C. use an evenhanded procedure to assign people to two or more treatment conditions
D. directly control or manipulate changes in the independent variable

Correct answer: A

Rationale: In a correlational design, researchers gather information on individuals without altering their experiences. Correlational studies examine the relationship between two or more variables without any manipulation or control by the researchers. The researchers simply observe and measure the variables of interest without intervening in any way. Choices B, C, and D are incorrect because they describe aspects related to experimental designs rather than correlational designs. In an experimental design, researchers manipulate variables, assign participants to different treatment conditions, and control changes in the independent variable, which is not the case in correlational studies.

5. Piaget's critics point out that __________.

A. he overestimated the competencies of infants and young children
B. his stagewise account pays insufficient attention to social and cultural influences
C. discovery learning rather than adult teaching is the best way to foster development
D. children's performances on Piagetian tasks cannot be improved with training

Correct answer: B

Rationale: Piaget's critics point out that his stagewise account pays insufficient attention to social and cultural influences. Critics argue that Piaget's theory does not fully consider the impact of social interactions, cultural differences, and individual experiences on children's cognitive development. They believe that these factors play a crucial role in shaping a child's thinking and problem-solving abilities, which should be given more emphasis. Choice A is incorrect because Piaget's critics do not focus on him overestimating the competencies of infants and young children. Choice C is incorrect as it discusses a different aspect of learning rather than the critique of Piaget's theory. Choice D is also incorrect since critics do not argue that children's performances on Piagetian tasks cannot be improved with training.
